GDB and ARM Multi-Ice JTAG emulator

GDB and ARM Multi-Ice JTAG emulator

[cyril.germond]

Hello,

I am (and as far as I know, there are quite a few other guys in the same area) working on a Linux port on ARM-based platform.
All this stuff implies a lot of free software: Linux kernel, GNU toolchain...
But also some hardware kind of material to access the target.
We use a JTAG device emulator from ARM-Ltd, called Multi-Ice for debug and various purposes ETM, etc...).

Apparently - and this is very disapointing - it is not possible (for the moment) to use gdb with Multi-Ice.

A few weeks ago, I got a message from KeithS (Redhat)
http://sources.redhat.com/ml/insight/2001-q1/msg00166.html

People from ARM told me that the work for using Multi-ICE with GDB had basically been done.
ARM has the RDI header files that are necessary  (available through the ARM Developer Zone - www.armdevzone.com).

I have heard that people from Cygnus/Redhat  had worked on the topic...

Does anyone knows if there is there anything on the roadmap, either within the gdb group, Redhat or anyone else?

Thanks and regards,

I'm not familiar with the Multi-ICE debugger, but if it uses the RDI protocol 
it should work the gdb. I've used a semi-hosted devboard and the Jeeni with 
gdb, both of which use the RDI protocol.
If it's not too late for your debugger choice, I've found the BDI2000 to be a 
good debugger that uses the native gdb protocol. (although the Jeeni worked 
quite well for me as well, but if you have any problems RDI just isn't as 
well supported in gdb sometimes).

Cheers,
Shaun

It doesn't.  It uses a proprietary protocol that ARM is
unwilliing to divulge.  Apparently they are now willing to let
people use gdb to talk via TCP to their Multi-ICE server
program that runs under Windows and knows how to talk to the
thing. I usually recommend that people avoid Multi-ICE because
it is a closed, proprietary system.
